Using GNU sort to sort a list by IP address |
My daily work requires me to work with a lot of customer data and much of it involves IP address allocations. If you find that you need to sort a list by IP address with GNU sort on a Linux server, just use these handy arguments for sort:
sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4 somefile.txt
For this to work, the file you're sorting needs to have the IP address as the first item on each line.
